The dust-guard herein described, com-` prising the packing-section and the frame or brace applied to the face thereof and composed ofsegmental sections connected to form a ring-like brace, substantially as set forth.

3. A dust-guard comprising a packing-section and a ring-like brace applied to the face of said section and composed of segmental sections overlapped at their ends and united together and to the packing-section, and corrugated longitudinally and provided at their inner and outer edges with portions projecting into the packing-section, whereby to compress the same, substantially as set forth.

4. A dust-guard comprising the packingsection, a brace applied to the face thereof and composed of segmental sections overlapping each other at their ends, and the rivets ,passing through said overlapping ends and through the packing-section, substantially as set forth.

5. A dust-guard having a packing-section and the brace applied to the face of said packing-section and composed of segmental sections corrugated longitudinally and united at their ends, substantially as set forth.

(l. A dust guard comprising a ring -like packing-section and the brace applied to the face of the packing-section and provided at its edge with an inwardly-curving portion by which to compress the packing-section, substantially as set forth.

7. A dust guard comprising a ring like packingsection, and ring-like brace-frame applied to the opposite faces thereof and having flaring iianges or wings at their inner ends forming tapering recesses for the inner edges of the packing, substantially as set forth.

8. A dust-guard composed of the packingsection, and the ring-like 'brace or frame applied to the faces of the packing-section and composed of sections united together at their ends and made wider at one end than at the other and corrugatedlongitudinally, substautially as set forth.
